OPERATION

CONFIGURING THE 1/4” INPUT JACKS AS DIRECT OUTPUTS

The eight 1/4” Input jacks come from the factory conﬁgured as line inputs and are electrically mixed with the XLR jacks. They may be used together if desired. To conﬁgure a channel’s 1/4” jack as a Direct Out, ﬁrst remove the RM82 lid. For each channel there are dual three-pin headers with shorting jumper on two pins. The setting from the factory is on “IN”. By moving the shorting jumpers to the conﬁguration shown as “OUT” (one jumper up, the other down), the jack then becomes a Direct Output.

CONFIGURING THE 1/4” INPUT JACKS AS INSERTS

To conﬁgure a channel’s 1/4” jack as an Insert, ﬁrst remove the RM82 lid and locate the corresponding channel’s dual three-pin header. Move both shorting jumpers down as shown below as “INSRT”, the jack then becomes an Insert.

CONFIGURING THE OUTPUT FOR MIC OR LINE LEVEL

The RM82 ships from the factory with the XLR Main Output conﬁgured as Line Level (+4 dB). To change this to Mic Level (-10 dB), carefully remove the lid, locate the Mic/Line header which is near the Main Output jack. Move the two jumpers from the Line Level position (shown below on the right), to the Mic Level position (shown on the left).
